IEEE Access invites manuscript submissions in the area of New Waveform Design and Air-Interface for Future Heterogeneous Network towards 5G.
Unprecedented levels of spectral and energy efficiency are expected from next generation wireless networks to achieve ubiquitous communications between anybody, anything, and at any time. Fifth generation (5G) radio access technology is expected to take a huge leap compared to the previous radio generations by supporting cognitive radio, machine type communication, the internet of things, besides traditional mobile broadband access.
The necessity of supporting the new services targeted by 5G has brought researchers to question the suitability of the orthogonal frequency-division multiplexing (OFDM) waveform as adopted in Long Term Evolution (LTE). However, the demerits of OFDM are recognized to be its large out-of –band emissions, which affect the coexistence of asynchronous services or devices, as well as its sensitivity to phase noise, Doppler frequency shift and large peak-to-average power ratio (PAPR).
Significant research effort is currently spent on the design and analysis of alternative solutions aimed at overcoming the inefficiencies of present waveforms. Candidate multicarrier solutions rely on different degrees of filtering for obtaining lower side lobes than OFDM, thus improving robustness to asynchronous transmission. For example, in filter bank multicarrier (FBMC) approaches, universal filter multicarrier (UFMC), Generalized frequency-division multiplexing (GFDM). Even though the mentioned solutions offer undeniable advantages in terms of spectrum containment, their suitability as 5G waveforms when considering complexity constraints as well as realistic impairments is still disputable. In particular, the extension to multiple-input multiple-output (MIMO) antenna transmission with multiple streams seems rather cumbersome. Thus this will lay down and interdisciplinary research agenda that combines energy and time efficient spectrum schemes into waveform design.
The goal of this Special Section in IEEE Access is to publish the most recent results in new waveform design and air-interface for future heterogeneous network towards 5G. Review articles on this topic are also welcome. The topics of interest include, but are not limited to:
We also highly recommend the submission of multimedia with each article as it significantly increases the visibility, downloads, and citations of articles.
